I'm toying with the idea of DIYing a version of this ceiling lamp
. Can anyone tell me the technical name for the pivoting/rotating/swiveling T joints, as Googling combinations of that phrase is not giving me similar connectors? [more inside]

We have this furnace
. In the summer it would be nice if we could run only the fan (We don't have central air), but according to the manual, Fan Only Mode requires the R and G thermostat contacts be wired. As you can see, only the RC/RH and W contacts are wired
. Would simply swapping the orange wire from RC/RH to RH/G create the circuit needed for sweet, sweet fan action, or will it be necessary to run a new wire from G to the control board in the furnace, therefore requiring professional help? [more inside]

While snooping around my basement today I found a strange little box/connector of some sort that I have no idea what it is. It looks really old (the house is ~90 years old) and isn't currently connected to anything. It seems
to correspond to the incoming phone line from the outside box, but I could be mistaken. Can anyone tell me what exactly this is? [img inside] [more inside]

YANM medical billing professional, but I need help in getting my very expensive, recently-out-of-warranty electric wheelchair fixed. I live in NY, have (crappy) private insurance ( Oxford Liberty) through my mother's job and Medicaid due to a cerebral palsy diagnosis. My chair ( an Invacare model) was provided through my previous insurance and OL isn't accepted by the contractor that provided it. They take Medicaid, but refuse to put in a claim and keep passing the buck. I can't leave my house. What do I do? [more inside]

I have a Frigidaire dehumidifier with a short (when I plug it in, it trips the fuse on any house circuit I try). Should I try to fix it, or is it likely to be unobvious? I'm not particularly handy, but I don't mind taking something apart. Is it safer/better to simply dispose of it? If so, is it recyclable?

When I'm sitting in the room with the breaker box to my house, I hear a series of short buzzes, like "bzzzt." The noise seems to be coming from the breaker box, and I notice that a faceplate to one of the switches is missing (breakers were last switched off a month or two ago, when new heat pump was installed.). Here is (or should be) the image (if not, there's just copper surface where the breaker faceplate should be):

I'm interested in adapting this tutorial
and this tutorial
into a dress design. Basically, I want to keep the accelerometer as part of the design, but have lower profile lights and reduce the number of lines to two or three, somehow... I could solder two extra beads (right?) on but it would look better with just two or three beads/lines. What can I do? The accelerometer isn't super-required since I can just program sparkles, so losing that isn't completely off the table. [more inside]

One of our circuit breakers tripped, and it won't return to its "on" position. I push it toward "on," but it doesn't stay, just returns to a middle position between on and off. It serves only a single hallway in the home, and nothing is plugged in there. Does the breaker need to be replaced? Should I call an electrician?

I don't really understand the utility industry very much but I've noticed some electric companies are very responsive to getting lines up from damage and have crews out at 2 a.m., and others don't even start work until the next day. What motivates them? Is it primarily loss of earnings from all the meters not running? Are there regulatory performance expectations? Or is there some sort of precedent in litigation that would put them at fault for underperforming? [more inside]

I am attempting to add one electrical outlet to my attic wiring. After installation there is enough power to the outlet to set-off a wire tester but not enough power to run anything plugged into the outlet. If there are any electricians or experienced DIY'ers around who could take a look at the wiring diagrams I made and see if anything is obviously wrong it would be much appreciated. Or, if you know of any forums where I could post the diagrams for help that would be good too. [more inside]

My monorail track lighting
stopped working. All of the lamps work if I push a little on one of the lampshades (making better contact with the track or something?) but only for as long as I'm pushing. I have already tried removing all the lamps from the railing, cleaning the railing and the contacts of the lamps, and making sure they are all screwed on as tightly as possible, as well as making sure the thingees that hold up the track are all screwed in as tightly as possible also. What should I be trying next? Thank you!

I heard this weird buzzing sound coming from my basement today, and I eventually opened up the ceiling and traced it to this transformer or something that's up in there. I tapped it with a piece of non-conductive material and it stopped buzzing. Tapped it again, it started buzzing more quietly, and then I tapped it again and it was silent. Anyone have any idea what this is, and why it's there? The house is from 1952 and doesn't have any electrical issues that I know of. Pictures:

We had an electrical incident where I work a couple of nights ago, and I'm trying to wrap my brain around it. Our house engineers have maintained systems at 150 amps on legs with 200 amp fuses. The power company reported a power dip, shortly after which we blew two of the 200 amp fuses. What happened? We had a drop in available voltage, so our amperage demand shot up? [more inside]

I want to attach the multimeter probes to the wires that power my front light, and see what, if any, power comes through those wires when I spin the wheel.
What do I set on the multimeter to see that happen? PS: I know nothing

Is there a method or device that will determine the amp rating of a fuse? I know that most fuses are marked with their specific amp rating, but I really need a way to verify. These are standard 5mm and 6.3mm fuses used in consumer level audio equipment. TIA

The front passenger speaker and window control stopped working on my Ford Crown Victoria. The front passenger power lock switch is working fine. The window itself works normally and I can lower it from the driver side control panel.
I had to take the whole dashboard apart earlier to replace a heater core so I unplugged a lot of wires. What did I miss when putting it back together? Where do I look?

We had lots of wiring replaced recently, including two lamps connected to a dimmer switch; the dimmer was also replaced. Yesterday we noticed that the dimmer was now only allowing fully on or off. Today the light went off with a loud popping sound and a visible spark from one of the lamps, though both bulbs themselves work fine. What happened and how do I fix it? Is it likely just a faulty dimmer switch? Do I need to turn off the circuit (which has many other lights on it) as a precaution?

The electric smoker that I was so excited about last week
doesn't work! After I plug it in, it runs for about 5 minutes before tripping the GFCI outlet that I had it plugged into. I did have it on a 10 foot long extension cord (no electrical outlets on my back porch). I assume this means there is a short somewhere? [more inside]

I learned today that it's dangerous to store combustibles such as clothing near the fuse box or electrical intake. I keep my off-season wardrobe under the stairs, and the electrical intake/fuse box is also under the stairs. How far away do I need to keep this stuff? What is a safe distance?
Is it feasible to use compact-o-stuff vacuum bags to reduce the crowding in the understair cupboard? [more inside]

Most SAD therapy lights are somewhere between utilitarian and ugly in terms of design. I want one that is beautiful, such that you could actually design a room around it. I think I would probably need to have it custom made, but I don't even know what sort of person I would begin trying to talk to. Let's ignore the question of cost for the time being, where would I find a person with the requisite skills (lighting, electrical, design, etc...) to build this for me?

Looking for a good overview for a proposed audio/visual, security and computer layout in an urban residence. e.g. list of equipment, layout, controls, outlets, wiring, speakers.
This is new, not retro-fit, the walls are open, all the wiring and controls can be neatly coordinated.
Help me see this in plan; as a well-tuned clock; not a mish-mash.
